I was walking to laundry room at about 3:45 pm and about 15 feet before I walked in I looked up and saw round shiny object going east at a high rate of speed. after watching it for 2 seconds it flew at a 45 degree angle up and just turned smaller and a fine white tiny spot and I could not see it any more. sighting last no more than 4 seconds. was flying 10-15 times faster than a passenger airline at 30,000 ft. when it flew up at a 45 degree angle it flew much faster.no clouds or planes in the sky at time of sighting.
